The normal (Perlish, elegant) way of doing list references would be as follows:
# Save our place.
push @stack, [$i, $curlvl, \@thisBOM];
...
# Now, recover where we left off.
($i, $curlvl, $raBOM) = @{pop @stack};
...
print "$i: @{$raBOM->[$i]}\n";
I believe it has the added bonus of not copying

This is a neat trick:
use Template;
my $template = Template->new || die $T
@{$_} dereferences the array reference created with []. For instance,
my $ref = [1,2,3];
is the same as
my @arr = (1,2,3);
my $ref = [EMAIL PROTECTED];
To access the array (1,2,3) using $ref, you need to say @{$ref} or, to
access an individual element of it, you can say $ref->[0], $ref->[1],
etc.

Thanks to all those who helped, so far! :-)
foreach ( @array ) {
print join ( ", ", @{$_} ), "\n";
}
This is the nice easy print statement I was looking for, but I don't quite
understand it. I get the print, and the join, bu
tell it's an array ref
b) find out how big it is (easily)
c) have in interpolated
all using the dereferencing syntax.

Going back to the array:

Guys,
This script:
use strict;
use warnings;
my @array;
for (0..3) {
push @array, ["$_:", 1, 2, 3];
}
for (0..$#array) {
my $row = $_;
for (0..3) {
my $col = $_;
print "$array[$row][$col], " unless ($col == 3);
print "$array[$
my @array = map { ["$_:", 1, 2, 3] } (0..3);
foreach (@array) { print join (', ', @{$_}) . "\n"; }
HTH,
David
